,l IMPROVEMENT IN PAPER-COLLAR MACHI'NES.

' Specification forming part of Letters Patent No.'19,927, dated September lvZ, 1.865.

To all whom it 'may' concern V v Beit known that we, SAMUEL SHEPHERD and AMMI M; GEORGE., both of Nashua, in the county ot' Hillsborough and State of New Hampshire, haveinven ted certain new and usel'ul Improvements in Machinery for the Manu facture of Paper Collars, Wristbands, Cuffs, and other Articles of Similar Nature, aiidwe do hereby'deciare that the followiiigfi's 'afulh clear, and exact description ot" the sa1ne,re`f erence being l d tothe accompanying draw ings, forming part ot' this specitication, in which- Figure lis a Vfront elevation of a machine. constructed according to our invention. Fig. 2 is a central vertical section-of the same in a plane parallel with Fig. 1. Fig.`3 is a transverse section of the cutting and embossing' rolls.

Fig. 4 is an axial section of one ofthe cutters,l

and ot' the ringby which itis heldin place. i Fig.

5 is a face view ot'a collar cut by the machine..

Similar letters of reference indicate corre'- sponding parts in the severaligures.

This invention consists in'ainachineforcutting out paper collars and other articles of a similar nature, cutting the button-holes therein and embossing the surface thereof in imitation of stitching at one opera-tion, the principal elements of which are apairot'. rollers with attached revolving cutters, punches, dies,and embossing-surfaces, the whole combined, ar'- ranged, and organized to operate as hereinafter described.

- A is a bedplate, having erected upon it two standards, B B, in which are received the boxes a a a. la for the journals c c c c of the pair of rollers C C', which are arranged one above the other and gearedtogether byapair standards B B, under the control ofpressure springs D D, which act upon 'them to press 4down the latter roller .upon the lower one, or

upon a sheet or strip of paper placed between the two rollers.

The pressure of the springs D Dis regulated the top of' the-standards B B.

The rollers may be made ot' steel, but are represented in Figs. 2 and 3 as made of iron, and fitted with steel bands d d', which are keyed on to them to form bard smooth-working peripherical faces, the circumferencesof which somewhat Vexceed the length ofthe collars or other articles to be cut.

'At the opposite end of its band d' or working-face'the upper roller, C', is iitted with rotary cutters e e,ccnsistingot rings of steel having sharp edges, which overlap sharp edges f f formed at the ends ot' the working-face of the lower roller, the said cutters combining with the said edges ff to form two .pairs of rotary shears to cut paper or other material passingv between the two rollers to a prcperwidth and longitudinal profile to form the collars or other articles. When the collarsvor other articles to be cut are intended tol have their edges par.

. allel'the edges f f and. the lapping edges of the cutters e e' will be in planes perpendicular to the axis of the rollers ;but wheu the said articles are to have their edges curved the said -edges will be so formed that if projected on ,a plane vthey would present the requisite curvature.

The cutters represented areintended to produce a collar of the form represented in Fig. 5,

hence the edge of the cutter e at'the left-hand end (see Figs. 1 and 2) and the corresponding edge fare in planes perpendicularto. the axis ofthe rollers to cut the' straight edge of the collar, andthe edgeot' the 'cutter e at-the right hand end of the corresponding cutting-edge j' ture ofthe other'edge of the collar.

to the proper shape, two cutters, gg, are inserted into grooves provided across the face 9i' the upper roller, C', the said cuttersbeing parallel with the axis ot' the roller, or oblique thereto, as shown in Fig, 1, according 'as the ends ot' the collar or other article are to.' be .atA right angles with or oblique to the longitudinal edges.

in combination with the sharp edges of two by screws E E fitted to caps F F secured on 'havin g one straightand one curved edge, and v are curved to conform to the required curvav V To provide for the4 cutting of the collar or -1 other article to the desired length and its ends These cutters operatewith a shears-like action, l

' grooves, h h, correspondently arranged in and across the working-faces of the lower roller C.

To produce theimitation of stitching on\the collar or other article male embossing-dies are provided upon the upper roller, (3",and` female embossing-dies in the lower roller, U. These. male dies may' cons-ist of rings or strips-hav` ingv toothed edges,ro'r of vpins inserted into the' one roller, and the iemaile dies 'of grooves or holes in the-other roller.

ln the, example of our invention represented the maledie for producing the appearance of stitching lengthwise of the collaror other article consists of a toothed ring, i, havinga lateral curvature corresponding-.withthat of the roterycutterje'yand is fitted between theV end i'aceofthe band d-and apackinga'ingJ,having n correspondinglateral curvature-and the female die 'consists simply of a groove,k,having a corresponding lateral curvature c'ut around.

the peripheryof the baud (l of the lower roller. f The linale'dies' for producing the imitation of 4 stitching along theends of the collar consist of pins I-I. inserted and secured in the `bund d of the upper 'rollerparallelwitli the' cutters g Ag, and jthe'cdrresponding female dies consist of holes m in in the band d of the lower roller.

The bands r1, d of the two rollers, and the cutters e e and diej oirthe upper roller,"are held in place by packing-rings 1l y screwed onto scre\v-.threads q q" 0n the right-hand journals ot' their respectiverollers, the said nuts holding the hands d d against shoulders r rl-on their respective rollers, and the packing-rings, n fn', having ,their inner sides curved laterally ,to coliform to the curvature of the' right-hand cutters e-andj', and their outer faces dat and perpendicular to the axis of the rollers. y The punches s't'or cuttingthe butt0nholes are' secured in or forined upon the band d of the upper roller, and the corresponding dies't t, in conjunction with which the said punches operate, consist'of liolosin thcband d ot' the lower roller, with lateral openings u through the rollers,E as sho-wn in Figs; 2 and 3, for they clearance and escape ot' the burrs cut out in cutting the- Dutton-holes. These pnnchesnnd dies are to be on and -inther'olle'rs themselves when the rollers are madeot' steel without theV bandsold. v

' v The operati-on of theniachne-is asfollows: The paper or other material fr o`ni .\`vnich the collars or other articles are/to beanade isijiirst' eut `Ifrom a roll otfanylengtlr'intostips of 'a' width somewhat greater. than thatrequiredtbr ,the said articles, and 'on the roller being set'in motion and the end oa-strip being presented betweenthexn the strip is drawn between theV rollers by their rotary motion and cut up into pieces ot' such length, width, and form as to pro. lduce the collars or articles desired, the proper` v'idth and longitudi-nalproile being produced by tlie, cutters e e, and the proper lengthand -forln of the-ends being produced by the cuttingfedges of gig, and h la. i At thesanie t'iin-ethe embossing, to represent stitches, is produced lby the dies'fi Irl m, and the button-.holesureout by the -punches s s anddies tf. 'l

By making the-rollerslofsuicint length in' an axial direction and furnishing-them -witlifa suitablenumberot' cutters, embossing-dieser@ `button-holecutting pane-hrs anddies,fa roll ol' proper or suitable width may be so cut npas to produce two or more collars or other articles at once, thesaid articles beingcut'sidebye side,v

twoor more from the width of thepaper.'

-What ,we claim as 'our invention, and desire to. secure by Letters Patent, is-

A machine forcutting out, punching the button-holcs in, and embossing nu .imitation ot' v stitching on paper-collars, composed ot'a pair of rollers, C .OQ furnished with steel hands l fl', cutting-rings e @'elnbossingrings i,`packing' rin gs j u u',punches s s, and d icsff 1, the whole constructed 4and operating substantially herein specified.'
